GBNtJS AN0T1TB8. l03 



Vein on both faces, also the margin uncinate-aculeolate : pedicels 

 slender, short, rigid, glandular-hirtellous, as also the narrow 

 calyx, this with deltoid hardly acute teeth: limb of petals only 

 deeply obcordate, the lobes being short and rounded, the base of 

 the limb marked by a pair of small scales representing the crown. 

 Southern Colorado, Baker, Earle & Tracy, n. 37, Mancos, 1898. 

 Also fine specimens from Middle Park, 1891, by Beardslee & 

 Kofoid, in U. S. Herb., and again by Frank Tweedy, from 

 Ridgway, 1895. 



13. A. DiscuERENS. Low, decumbent, forming colonies by 

 an extensiye system of rootstocks all connected, the very slender 

 weak stems decumbent or more depressed, very leafy, with inter- 

 nodes much shorter than the long narrow leaves, the lower villous 

 with more or less definitely retrorse hairs, the upper with a 

 firmer viscid spreading pubescence, but gland-tipped hairs 

 wanting or obscure: leaves thin, oblanceolate, acute, 1 to IJ 

 inches long, sparsely roughish-pubescent or merely puncticulate, 

 but midvein and margin uncinate-hispidulous : flowers very few 

 among the upper leaves, on filiform pedicels not surpassing the 

 foliage : calyx -teeth triangular-lanceolate, almost acuminate : 

 petals bifid, their lobes round-obovate and with a tooth on the 

 side. 



Gunnison, Colorado, 23 July, 1901, C. F. Baker, n. 559; also 

 perhaps the same is the Los Pinos plant of Mr. Baker's 1899 

 collection sent out under 'n. 313. 



14. A. ELLIPTICA. Extensive underground growth as in the 

 last, the rootstocks stouter, less prolific of aerial stems, these 

 mostly simple, 2 to 5 inches high, retrorsely short-pubescent, 

 the uppermost, as well as pedicels and calyx densely viscid-glan 

 dular: leaves thin, elliptical, J to 1 inch long, acute, smooth 

 and glabrouson both faces, only the margins and midvein beneath 

 beset with very short uncinate hairs : calyx-teeth ovate, obtuse, 

 ciliolate, the subcylindric tube hirtellous-glan dular. 



Alpine in the mountains of southern Colorado, on Bob Creek, 

 west of Mt. Hesperus, July, 1898, Baker, Earle & Tracy, n. 272 

 as in my herbarium.
